Reference and vehicle check
Compare the primary OE reference and any alternate numbers with the exact vehicle application. Model year alone may be insufficient when a production change occurs within the same year.
- OE and alternate references
- VIN or chassis where available
- Engine
- Production date
- Left- or right-hand-drive market when relevant
Dimension and connection check
Measure the core separately from the overall assembly and note the measurement method. Confirm inlet and outlet positions, fitting shape, pipe angle, receiver-drier position, and any pressure-sensor port.
- Core width, height and thickness
- Overall mounting span
- Connection position and type
- Receiver-drier side
- Bracket and sensor provisions
Approval before volume ordering
For a new or uncertain application, confirm drawings, detailed photos, or a sample before volume supply. Record the approved reference so later orders use the same basis.
